It's the X-Men vs. Magneto. 'Nuff Said!
In Miami, a nuclear power plant explodes in response to Magneto's supercharged manipulation. Far away, his Arctic Citadel is under attack by the military and he has the X-Men at his mercy in his control room.
As the X-Men battle for their lives, Professor X and the other escapees from Camp X-Factor race against time to contain the damage from the nuclear meltdown.
